Cherry tree named ‘Glenred’

ABSTRACT

The present invention relates to a cherry tree,  Prunus avium , and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, self-sterile but very productive and regular bearing tree. The fruit matures in the early season approximately in the second week in May under the ecological conditions described, with first picking on May 9, 2000. The fruit is uniformly large in size, very sweet in flavor, very firm and crisp in texture, entirely red in skin color, virtually non-doubling and somewhat resistant to skin cracking due to rain. The variety was a first generation cross using ‘Tulare’ (U.S. Plant Pat. No. 6,407) cherry as the seed parent and ‘Brooks’ (U.S. Plant Pat. No. 6,676) cherry as the selected pollen parent.

BACKGROUND OF THE VARIETY

In a continuing effort to improve the quality of fresh market andshipping fruits, I, the inventor, typically hybridize a large number ofnectarine, peach, apricot, plum and cherry seedlings each year. Thepresent invention relates to a new and distinct variety of cherry tree,which has been denominated varietally as ‘GLENRED’ cherry. The presentvariety resulted from a seedling hybridized by me in 1992 and planted ina cultivated area of my experimental orchard near Le Grand, Calif. inMerced County (San Joaquin Valley). The variety was a first generationcross using ‘Tulare’ (U.S. Plant Pat. No. 6,407) cherry as the seedparent and ‘Brooks’ (U.S. Plant Pat. No. 6,676) cherry as the selectedpollen parent. Subsequent to origination of the present variety ofcherry tree, I asexually reproduced it by budding and grafting on Colt(U.S. Plant Pat. No. 4,059) cherry rootstock in the experimental orcharddescribed above, and such reproduction of plant and fruitcharacteristics were true to the original plant in all respects.

The present variety is similar to its seed parent, ‘Tulare’, byproducing early maturing fruit that is full red in skin color andvirtually non-doubling, but is distinguished therefrom and animprovement thereon by being more vigorous in growth with a uniquehorizontal limb structure and by producing fruit that is larger in size,sweeter and milder in flavor, crispier in texture, and about 8 daysearlier in maturing.

The present variety is similar to its pollen seed parent, ‘Brooks’, byproducing early maturing fruit that is large, full red in skin color,and virtually non-doubling, but is distinguished therefrom and animprovement thereon by blooming about one week earlier, by possessingthe natural horizontal limb structure and by producing fruit that isdarker in flesh color, has a much longer stem, ripens about 4 daysearlier and is considerably more resistant to skin cracking due to rain.

DRAWING

The accompanying color photograph displays a characteristic twig bearingleaves and a bunch of cherries, several fruits removed from the branchwith the stems attached, several whole fruits detached from the stems toexhibit the skin color and form, a fruit sectioned transverse to thesuture plane to reveal the flesh and fibers, and a few stones, alltypical of the subject variety.

POMOLOGICAL CHARACTERISTICS

Referring now more specifically to the pomological characteristics ofthis new and distinct variety of cherry tree, the following has beenobserved under the ecological conditions prevailing near Le Grand,Merced County (San Joaquin Valley), Calif., and was developed at thestate of shipping ripe on May 13, 2000. All major color codedesignations are by reference to the Inter-Society Color Council,National Bureau of Standards. Common color names are also usedoccasionally.

TREE

Size: Large, reaching a height of 14′ [4.27 meters] by the 3rd year ofgrowth on Colt rootstock.

Vigor: Very vigorous, responding aggressively to irrigation andfertilization. The variety should be grown on a standard commercialrootstock for production purposes.

Growth: Upright.

Although the new variety of cherry tree possesses the describedcharacteristics under the ecological conditions at Le Grand, Calif., inthe central part of the San Joaquin Valley, it is to be expected thatvariations in these characteristics may occur when farmed in areas withdifferent climatic conditions, different soil types, and/or varyingcultural practices.

I claim:
 1. A new and distinct variety of cherry tree, substantially asillustrated and described, that is similar to both its seed parent,‘Tulare’ (U.S. Plant Pat. No. 6,407), and its pollen parent, ‘Brooks’(U.S. Plant Pat. No. 6,676), by producing early maturing fruit that isfull red in skin color, very firm in texture and virtually non-doubling,but is distinguished from ‘Tulare’ and an improvement thereon by beingmore vigorous in growth and by producing fruit that is larger in size,sweeter and milder in flavor, crispier in texture, and about 8 daysearlier in maturing, and is distinguished from ‘Brooks’ and animprovement thereon by blooming about 7 days earlier and by producingfruit that is darker in flesh color, has a much longer stem, ripensabout 4 days earlier, and is considerably more resistant to skincracking due to rain.
